TRAVERSE-CORD FASTENER.

Specification of Letters Patent.

Application led July 22, 1916. Serial No. 110,665.

To all whom it may concern.'

Be it known that I, JOHN A. DONNELLY,

a citizen ot' the United States, and a resident.

ot the city of New York, borough of Manhattan, in the county and State et New York, have invented a new and improved Traverse-Cord Fastener, of which the following is a full, clear, and exact description.

This invention relates to supporting devices for portieres, curtains or the like and has particular' reference to means for attaching a traverse cord to the traverse rings of the drapery of the character indicated.

Among the objects ot the invention, therefore, is to provide a novel form of traverse ring or cord attachment Afor traverse rings enabling the traverse cord to be attached di-` rectly to the traverse rings by any member of the household, whether skilled or unskilled in this particular art.

A further object of the invention is to provide an attachment means for the traverse cord whereby the attachment oi the traverse cord with the traverse rings will be facilitated and the appearance of the drapery will be materially enhanced.

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details o1 construction disclosed or suggested herein, still for the purpose of illustrating a practical. embodiment thereof roteren ce is had to the accompanying drawings, in which like reference characters designate the same parts in theseveral views, and in 'which- Figure 1 shows a` liront elevaticm ot the supporting rod and parts n'iovali .ly supported thereon;

Fig. 2. is a detail view ol one of the traverse rings partly in section showing the construction of the preferred form of my improvement;

Fig. 3 is a tace view of the same ring with the cord attachment open;

Fig. l is a vertical transverse sectional detail on the line 4tl oit Fig. 2; and

Fig. 5 is a horizontal sectional view on the line 5--5 o1 Fig. 21.

Referring now more particularly to the drawings, .l show by way oit illustration ol a preferred means for carrying out the invention, a pole 10 supported at its ends as usual in the side posts 11 of an archway. Adjacent the ends of the pole are ixed pulley rings 1Q and 13, the former having two pulleys lil and 15, while the latter has a single pulley 16.

Remote trom the pulley rings are a pair ot traverse rings 17, to each or' which the traverse cord 18 is adapted to be clamped or anchored in a reliable manner. each of the pulley rings and the traverse ring on the same side olf the archway are a series oit idle supporting rings 19 of any suitable or well known construction. The curtains, portier-es or the like, indicated at 20, are supported upon or trom the rings above described by pins, hooks or the like, indicated at 2l.

in the usual practice of traverse cords and rings, the cord is tied around each of the traverse rings which requires special skill on the part ot the operator and considerable waste of time in assembling the parts, but when the tying is done by one who is unskilled much trouble ensues because ot the slippage ot the cord or the failure ot the drapery to operate as desired. As shown herein, the traverse cord 18 is threaded over one of the pulleys, say 14k, ot the ring 12, thence directly through the idle rings 19 and the traverse ring 17 on the same side of the arch, and thence through the adjacent traverse ring where it is clamped and thence it is extended through the remaining idle rings 19 on the opposite side, and thence around the pulley 1G in the opposite fixed pulley 13. rilhc cord is thence extended bzwkwardly through the rings 1l) and traverse ring on the saine side as the pulley 13, tlniuice to the traverse ring ou. the first side where it is clamped, and thence it is eze tended through the idle rings and over the pulley 15 on the lirst .mentioned side, the free ends ot the cord being provided with handles or tassels for manipulation. As shown in Fig. 1, a downward pull upon the tassel will cause the traverse ring 17 on the same side to be drawn directly toward the pulley 1:2 carrying with it the idle rings 19. At the same time `the cord by virtue oit the pulley 16 and the connection with the other traverse rin g will cause the latter traverse ring to move iu the op]' o, ;;ite direction, carrying with it the idle rings between it and the ring 13. l't will thus be seen that the portires or curtains 20 will be opened quickly and directly, moving 'from each other. The tassel 23 will move upwardly accordingly toward the ring 12. ln order to Between close the curtains, a downward pull upon the tassel Q3 will cause a movement of the traverse rings toward each other, returning the devices j'ni'niiptly and easily to the position shown in Fig. l. i

The traverse ring 17 may be made of any suitable structure or design. I provide a clamping device for the traverse cord of such a nature, however, that the internal diameter of the rings need be very slightly larger than the diameter of the pole 10.

'Each traverse ring is formed, as indicated herein, preferably at its bottom side with a depression 24 forming a pit or notch 24 at the deepest place. If the ring be made of sheet metal, this depression and notch may be formed by swaging the metal downwardly or outwardlyvwith respect to the center of the ring. The clamp shown herein comprises a jaw 25 extending into and secured in the depression and pit aforesaid and forming a seat for the cord 18. This fixed aw may be secured in place by soldering, brazing or by any other suitable positive permanent means. The clamp includes also a movable jaw 26 having integral connection atene end at` 27 with the fixed aw. The material of the clamp ispreferably spring metal and the movable jaw may have an inlierent` tendency to spring upwardly or inwardly away from the iixed jaw, as shown in Fig. 3, but the'free end of the movable jaw is adapted to be forced downwardly toward the adjacent end of the'fiXed jaw and there secured by some simple easily manipulated device, such as a keeper 28, in the form ofa ring slidable along the traverse ring. rIhre movable jaw is provided with a protection, 26 extending into or toward the seatv formedin' the Xed jaw for the cord for the purpose of increasing the grip on said cord. I also preferably rouglien or serrate the gripping surfaces of the jaws so as to make it practically impossible for the cord to slip when it is once secured.

In order to connect the cord to the traverse rings improved as herein described, the curtains are hung upon all of the rings as usual. The cord is then threaded through thev pulleys and rings as described, and then with the curtains adjusted as desired along the pole and the cord correspondingly positioned, the operator has but to slip the two portions of the traverse eordinto the clamps, each portion of the cord slipping freely beneath the movable jaw 26 when the keeper 28 is spaced therefrom. After the cord is in place, the operator brings the keeper down into frictional engagement with the clamp, asshown in Figs'. 2 and 5, and the operation is completed. Since there is nothing tending to loosen the keeper it is impossible for tliecord to slip in either direction th rou gli the clamps. Furthermore, p ractically noiierof the interior space of the rings is occupied by the clamping device. By this means I provide a much neater, as Vwell as a much more convenient traverse cord attachment than has heretofore been brought to my notice.

I cla-im:

f l. The herein described ing in one side a depression and. a` pit formed in the center thereof, yand a cord clamp having a relatively stationary jaw secured in said depression and' having at its center a depression extending and forming a-4 cord seat, said clamp including' a relatively movable j having spring connection at one end with thei stationarv jaw, and means, to bindfthe movable jaw in binding` engagement with the cord,

2. The combination with a traverse ring, of a traverse cord attachment Vmeans cooperating therewith, sarid, attachment means comprising a clamp having relatively xed and movable jaws formed1 of a single piece of spring material, the fixed jaw having a seat to receive the cordand'the movable jaw having a projection extending into said seat, said seat and projection being provided with serrations, and ineansserving` to hold the ree end of the movable jaw in gripping position. f
